[snip] > Well, if you can find where ssh is invoked, you can also give it the > "-n" parameter, which would result in equivalent functionality. I don't want to confuse anybody, the command in question is being run internally by ssh to setup an X authorization cookie to pass over the the xterm on the remote system. I did try -n to no avail. ssh -vvv -n -X target OpenSSH_4.2p1, OpenSSL 0.9.8a 11 Oct 2005 Pseudo-terminal will not be allocated because stdin is not a terminal. debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.0.100 [192.168.0.100] port 22. debug1: Connection established. ...snip... debug1: Authentication succeeded (password). debug2: fd 4 setting O_NONBLOCK debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug1: Entering interactive session. debug2: callback start debug2: x11_get_proto: /usr/X11R6/bin/xauth -f /tmp/ssh-1X7a4Jwi47/xauthfile generate 127.0.0.1:0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2>/dev/null The message I referenced earlier goes into some depth about x11_get_proto and how the xauth command above is being run: http://www.cygwin.com/ml/cygwin/2004-11/msg00626.html Perhaps popen is using a socket or named pipe???? I do appreciate the suggestions so far. I just don't yet understand how the installation and deinstallation of ZoneAlarm is effecting this behavior.
